Question

A vessel contains 10 moles of O2 and some other gases, total pressure is 10 atm, what is the partial pressure of O2?

(a) 1 atm

(b) 10 atm

(c) 100 atm

(d) Cannot be determined

This question was posed to me by my school teacher while I was bunking the class.

I'd like to ask this question from Ideal Gas Mixtures and Partial Pressure in division Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer 1

The correct answer is (d) Cannot be determined

The explanation is: Since the total moles are not given, fraction of O2 cannot be determined, so partial pressure of O2 cannot be determined.
